Has a warning light appeared on your dashboard?

If you notice a warning light on your dashboard, it may be beneficial to book in for a car diagnostic test at your local National Tyres and Autocare branch. Regular car checks are extremely important to ensure that your car is road legal and safe to drive. Routine car maintenance can also save you money in the long run. If you identify any issues with your car early on, this can prevent the issue from turning into something more serious, minimising the risk of a costly repair and serious engine faults.

Can I book a car diagnostic test if I don’t have a warning light?

It is important to understand that even if you do not have a warning light showing up on your dashboard, there may still be an issue with your vehicle. If you notice any issues with your car, for example, if the car jerks while you are shifting gears, then a car diagnostic machine will be able to run a full vehicle health diagnosis.

The SensorPad 8, the state of the art engine diagnostic tool used within National branches, will be able to individually check for any stored or current faults on your vehicle by identifying all of the modules connected to the engines ECU. Make sure that you don’t wait for a warning light to appear before booking in a Diagnostic test before if you feel that there is a problem.

What can a car diagnostic test tell you?

Diagnostic tests can help identify problems with the main components of a vehicle such as a car engine or brakes. A diagnostic check will also be able to help identify issues related to performance.

Before car diagnostic tests were common practice at your National branches, identifying faults was a timely and complicated process. However, thanks to technological enhancements, with the state of the art SensorPad 8 diagnostic tool, this can help detect issues long before they lead to serious issues. The car diagnostic test will also have access to previous car diagnostic codes, which will be able to tell you if the fault is current or historical. Any historical faults will be cleared from the engine control unit’s memory (ECU).

If you are purchasing a second-hand car, it may be a good idea to book in for a car diagnostic test to ensure there are no underlying issues before you hand over the money!
